Features:
1. Use of high-quality materials, quality assurance
2. Stable performance
3. Exquisite appearance
4. Charging during the day, automatically turn on the light at night, and automatically turn off the light at dawn, the output voltage is the output voltage when the battery has no voltage
5. The circuit controls the output by detecting the change in voltage generated by the solar panel, without the need for photosensitive elements
Wiring methods:
1. B + B connection of the lithium battery
2. S + S - connected to the solar panel
3.L+L-output
Wiring sequence:
1: connected to the lithium battery, the battery must have the corresponding protection plate
2: Connect the LED, the lithium battery is energized, the LED lights up
3: Connected to the solar panel. At this time, the solar panel glows, LED off, LED does not glow.
If you need to turn off the switch at night, or the switch interface SW has been reserved for transportation and storage, then you can install the switch.
Cautions:
1: The stable working output current of the control board cannot be greater than 600ma, otherwise it may cause output protection
2: charging and anti-reflow without overcharge and over-discharge protection lithium battery must be used with the corresponding protection board (cell phone batteries have 3.7v protection, more than 18650 no. 3.7v protection board can not be used in series)
3: pay attention to waterproof insulation
4: LED lights can not use boost drive
5: the controller battery voltage for the output voltage, no limit on the current and voltage limit, 2V3V LED lamp beads can not be used directly, need to be driven by the buck constant current or series current limiting resistor, the output current is the maximum operating current, not constant current
6: Output power is the actual power, please confirm the actual power consumption of the load before use
7: Direct access to 3Vled may damage the controller or LED
8: The battery must be equipped with a protection plate, the battery voltage must match the open circuit voltage of the solar panel
Warm tips:
1.0.5A version of the fuse will automatically protect at 0.6-0.7A, and automatically recover after the current is reduced
2.1A version fuse will protect automatically when the current is 2-3A and will recover automatically after the current is reduced (a small part will be burned permanently)
3.2A version of the fuse will be permanently blown at 4-5A
